The rolling motion of an unstabilized ship and a stabilized ship equipped with fin stabilizers has been predicted by use of a random wave model. Actual controller gain factors have been determined for the fin stabilizer and the system has been made simulated. The comparison of the simulation results with those of a real ship in motion indicates that the method can be used to predict the roll motion of a stabilized ship in random wave.
